Without doubt, flexibility will be a key component in the future of energy grids. Future grids will need to have the capability to react almost instantaneously to changes in loads to efficiently manage constantly fluctuating consumption and generation. On utility and DSO side, there is an expectation of a full suite of smart grid devices that match particular requirements. These needs will be shaped by a wide range of factors from population density to climate and geography. Some parts of the world produce a lot of wind power or have access to geothermal sources of energy. Colder regions need to monitor heating consumption, while warmer regions need accurate data on consumption of energy used for cooling. Thanks to cutting-edge solutions from Landis+Gyr, every region can have smart grids tailor-made to their needs in a way that maximizes the gains these technologies offer.
